The exact length of life after liver cancer surgery is related to the pathological type, malignancy degree, surgical method, postoperative care as well as physical and psychological quality of liver cancer. Clinically, most liver cancers are primary liver cancers with high malignancy and rapid progression of disease. If the tumor and surrounding metastatic lymph nodes can be completely removed and enough liver tissues are preserved, most patients have a survival period of about 2-5 years, with some up to 5 years or more. If the tumor cannot be completely removed, most of the patients’ survival is only a few months to a year. If early stage liver cancer can be surgically removed, the 5-year survival rate can reach 90%. The shortest post-operative survival for diffuse liver cancer in advanced stage or already multiple metastatic cancers in the liver can be 2-3 months. In general, patients who are young, physically fit and resistant will have a relatively longer survival period. Therefore, early screening of liver cancer is important, and early detection and early surgical treatment can effectively improve the postoperative survival rate. After surgery, patients should be monitored regularly and take medication as prescribed by doctors. In case of recurrence, patients should go to oncology or hepatobiliary surgery for retreatment in time, and some patients can undergo liver transplantation, which can prolong their survival time.
